A system for deaeration of a liquid comprises a heater for heating the liquid to a well-defined temperature, means for pressurizing the liquid, a first piping for guiding the heated liquid to a separation vessel, a vacuum pump for evacuating deaerated gases from the separation vessel, and a second piping for guiding the deaerated liquid from the separation vessel. The system further comprises an inert-gas supply and a mixer for supplying and mixing in inert gas into the liquid in the first piping. The vacuum pump is controllable to maintain a separation pressure in the separation vessel corresponding to a pressure at or slightly above the saturation pressure.

A detection, measuring and separation System of the light fractions in diathermic oil feeding an ORC (Organic Rankine Cycle) plant, by means of a circuit with a delivery conduit (12) and a return conduit (13). The System comprises a stripping receptacle (25), positioned downstream of the thermal group of the ORC System, means (24; 45) for an inlet of a flow of diathermic oil from the return conduit (13) of said circuit (11 ) to an inlet of the stripping receptacle, means (42, 46) Connecting an output of said stripping receptacle to the return conduit (13) of said circuit (11), a feeder (28) of an inert stripping gas in said receptacle to cause a separation of light fractions from the oil, and a drainage conduit (30) connected to said receptacle and configured to cool and collect the separated light fractions and to monitor the presence of specific pollutants contained in it.

Vapours are condensed in a plate heat exchanger composed of a frame including front and pressure plates between which are arranged suspended plates. Ued for condensing vapours yielded by polymerisation of chloroprene. Advantages are low thermal resistance, favourable flow conditions resulting in low tendency to clogging and low heat losses, high throughput in compact plant, good servicibility and low clearing costs.
